cutting' troubles so frequently experienced' with pneumatic tires now incommon use.

i further object is to provide a construction 'e of deflation may 'berun teinpore witi out removal ofthe tire from the rim and 'withoutdanger of uring the tire.

Jfurt tion whi her object is to provide a construccli will be selfsealingl against the entrance et moisture and dirt, thereby pre-wventing rusting and rendering the parts less liable to wear. f

l haife further ainiedto provide anarrangement by which `a single tubemay be used, thus avoiding the necessityrfor the double tube type citire heretofore'almostI exclusively used. l

Still another object is to grovii-ilefa construction which may bereadily appliedto and removed from the wheel rim.

tion is shown as applied, and which may be of the ordinary or anydesired construction, save that the telly lEl iS provided with a plaincylindrical periphery and with transverse bolt holes for the passage oithe securing bolts hereinafter described.

Detachably secured to this Jelly la is an annular tire seating orcarrying portion 2 formed yof two sections which are practicallyduplicates of each other. Each comprises a part, 2a which has an innerface curved to conform to the surface of the inflatable tube and, of anextent to overlie approximately one quarter of the surface of the tube,the two sections, when placed `upon the rim and in juxtaposition asshown, providing an annular channel approXiinately semi-circular incross section. o

The two sections are urther'provided with inwardly extending portions2", at the bases fof which are located outwardly turned anges 2C, theinner faces of which rest upon they outer periphery of the telly.

ll/ly preferred manner of securing the tire seat upon the elly is toprovide the margins ot the anges 2C with inwardly extended annularflanges 2d which embrace the telly between them and to which they aresecured by bolts 3 passing through alining openings in the flanges andtelly.

llhe bolts are preferably passed through from the inside or" the wheel,and while both sections may be readily removed from the telly asa matterof fact, after installation,

it is practically never necessary to remove more than the outer sectionwhich can be readilyand quickly done by unscrewing the nuts 3aandslipping` oil the corresponding section, leaving the other sectionand bolts` in place. l

llrithni the annular tire seating channel formed by the two sectionsalcove described is placed an annular inflatable member which ispreferably in the shape of an end-` less tube A of hose material, to witfabric and rubber, or of the character o' the siiiglev tube tires.

To protect this against puncture and the wear of the road l provide aprotecting armor comprising a plurality of strips of resilient metalindicated at 4 and 5, which are arranged to take the wear of the roadand are normally sustained by the pressure of the tube A, but can yieldinwardly by reason of their inherent resiliency and also by reason oftheir ends being arranged to have radial sliding movement toward andfrom the aXis of the wheel.

A manner of slidingly connecting said ends which I have found desirableis` to provide annular side members 6 which have their inner horizontaledge portions inserted in the channels formed between the parts 2 and 2,being held therein by screws 8 inserted through alining openings in theparts and tapped into the parts 2. are, ofcourse, inserted before theairtuloe is seated in position, and the heads ofthe screws areeountersunk as shown.

After the tire seat sections 2 and members have been applied theresilient tread members are applied. To enable them to be easily andquickly placed in position, and held firmly in use, I provide on eachside' of the tire a sectional carrying and secar` ing ring 9. Theserings are preferably eachv of two semi-circular segments which, whenassembled, ferm a complete ring, andr are provided with studs or rivetsl() which project through radial slots et and 5a in the plates-land 5,being headed on the inside to overlap the edges of the slotsas shown inFig. 3. i i

To enable the resilient members'te be individually disconnected from therings in case of 4wear or breakagethe slots may'have enlarged portionsas shown, sufficient te permit the passage cf the heads of the studs, or

said studs might bemade removablefrom the rings.

After the tread members are connected to the pairs 4of segments 9 thelatter are 1nserted from opposite `sides of thewheel be#- tweentheportions 2 and G and are secured by locking screws or screw bolts 13inserted in alining openings in the parts, the ends of thesegmentsabutting and forming com* plete rings.

To prevent moisture and dirt from `working in between the tread membersIprefer" to arrange them in two series, theumembers being arranged instaggered and overlap ping relation, the outerseries et i'overlapping.'the inner series 5, and to provide between The screws these a sealinglayer of rubber as indicated at l5.l y

In assembling, the outer members 4 Vwould first be placed in positionwith their slots engaging the studs; the-rubber sealing layer wouldthen'be placed in position, and thereafter the inner set of members 5would be secured in place, confining and compressing the rubber betweenthe two sets and sealing the peripheral surface.

Instead ofmaki-ngfthe resilient members integral throughout their entireextent I may make them of .sections hinged together as shown iin F igt5, `each havinga main resilient portion overlying the tread, and sidewingsfor'portions hinged to the main portionlas indicated -at 4b and 5l.

To fmake'the tread Ynon-slipping I may recess 'the' outer faces f of theresilient `members and fill such recesses with suitable antislipping`materialfsuch for examplev as carborundum, as'indieated at etc in Fig.6. In this form I have'shownzhowinstead of using two series ofoverlapping: tread members I may usea V-singlelayer of abutting-treadmembers in wliich'event I prefer to have i themy abut on abutting linesinclined alternately in opposite directions asindicated at 4d and 4c.;

If desired,-alayer orsheath of asbestos or like material, 16, maybeplaeed around the tube A to prevent rust action or damage thereto;Y

Having` described-my invention, what I claim'is:

In afresilient tire, a channely shaped rim, an inflatable tube seatedtherein, sectional rings locatedonfoppositesides of said -rim i withlmeans 1 for detachably' securing them thereto, `resilient treadv membersoverlying said iniiatabletube and havingV their ends lying withinsaidsectional rings, said` resilient `membershaving radial slots yintheir end portions; and studs proj eating-inwardly from theringsvand-en'gaging; the slots, said studshavingzheadson theinside ofthe resilientmembers and" said slots enlarged portions-to permit thepassage of thefheads.
